Even though they continue to act coy about it, there’s undeniable hot chemistry between Mark and Naya — they was plenty of hugging and holding going on between them at the Maxim Hot 100 party!

Mark Salling and his Glee co-star have stayed mum on their rumored budding relationship, but HollywoodLife.com witnessed the two actors getting awfully cuddly last night, May 19, during Maxim‘s Hot 100 Party at Paramount Studios — which just confirms now more than ever, there is definitely some sexual chemistry within the Glee cast!

“Anytime Naya had a chance, she was hugging, holding and being close to Mark Salling,” HollywoodLife.com’s <strong>Russ Weakland</strong> reports. “They were being very friendly, but I would honestly call it [friends with benefits] rather then a potential relationship rumor, because she left Mark alone and Mark was flirting with girls all night, he even danced to Snoop Dogg songs with a random girl who did not leave with Mark.”

Mark, 27, and Naya, 23, must not be THAT serious because minutes later he was flirting with Tila Tequila while shooting hoops on the basketball court.

“They had a a half court basketball court set-up and Mark loved it as he took off his hat to expose his mohawk,” Russ says. “He wasn’t very good at basketball but he tried to dunk multiple times till some people who were running the basketball court yelled at him to not do it because they didn’t want him to break the rim. He couldn’t dunk it anyway though so it was a lost cause. He kept missing shots as well. He actually started playing one on one with Tila Tequila and posed for pics with her, they flirted.”

Sounds like Mark should stick to music, because his game leaves much to be desired.

“He stayed for awhile till he shot an air ball and some girl said, ‘Man it must suck to suck,'” Russ continues, explaining, “I think that bruised his ego because moments later after being on the court for a good half hour, he left.”

Other stars at the party included The Bachelor‘s Jake Pavelka and Vienna Girardi, Heather Morris, Nicole Scherzinger and Ciara.
